Using the CC on the highway, long trips, is an ideal situation, however, the CC is being used at other times while driving. One of the most dangerous situations, is when the resume button is used to get back to the previous set speed and the road conditions are not ideal for it's use. If the roads are slick, black ice, an unknown situation...and the CC is resumed after a stop, the car will spin out of control because the rear tires are spinning to get to the set speed. There are probably many accidents when the CC was being used, and were not noted that CC was involved, unless there was an investigation....Yes there is some data here and there, supporting this dangerous issue however, not enough in my opinion. This is a very new topic on safety issues....In the meantime, warn as many people as you can of the safe usage of CC! You may save a life...
